Abstract
In one embodiment there is provided an ambient lighting control systemcomprising a controller () and a sensor node (). The sensor node () comprises an arrangement including a light energy collecting element () such as a solar cell, an energy storage element () and a transmitter (). The collecting element () charges the storage element (). The transmitter () is arranged to transmit signals to the controller () using energy stored by the energy storage element (), wherein the number of signals provided during a time interval to the controller () is proportional to a light intensity at the light energy collecting element (). The controller () may thus output a control signal C for controlling an amount of ambient lighting, wherein the control signal is based on the determined number of received signals.
